The upper series of rolls is mounted is curved. Further, there is provided no upon a swinging frame comprising two slde means for properly setting the knife to the members 21 connected by cross pieces 23 and 55 discharge throat cutting plate either when 24 and journaled on opposite sides of the 119 frame 1 about an axis 25 at the intake of the feeding mechanism. Turning about an aXis common to the axis of the swinging frame, is a gear 26 which meshes with the pinion 20 and is connected to idler 27 geared to pinion 29 of the first upper roll and to the pinion 28 of the second upper roll, the second roll pinion 28 being geared to the third or last roll pinion 30, by means of an idler 31. It will be noted that the gear 26 gears directly to the first lower roll and is connected to the first upper roll by an idler, thus causing the rotation of the gear 26 during feeding, in a direction that will tend to lift the swinging frame and thus to prevent the breaking of any parts when the feeding rolls become clogged. The freely swinging frame carrying the upper series of rolls is yieldingly held in its lower position by means of a weight adjustably mounted on an arm 66 bifurcated at one end to provide two arms 67 pivoted at 68 to the frame of the machine and connected by links 69 to the swinging roll frame.

Cutting nechcnism.The tobacco passes from the feeding rolls through a discharge throat 32 having a cutting plate 33 surrounding the same, the plate being mounted on a front plate 34. At opposite ends of the front plate are provided bearings 35 on each of which is pivoted intermediate its ends a link or lever 36. Each link or lever is provided on one side of its pivot with a pocket 37 seen best in Fig. 5 while the front plate is provided with a pocket 38 beneath each link or lever. Each pocket 38 contains a helical spring 39 which also seats in the pocket 37 of one of the links or levers. The upper end of the links or levers, that is, the ends opposite those which the springs 39 engage, are provided with bearings 41 on which are pivoted the back plates 42 of the oscillating knife frame, the back plates 42 being connected. by a front plate 43 which is spaced from the back plates to permit a knife holder 44 to reciprocate between them. The knife holder 44 is guided in the oscillating frame by a link 45 which is pivoted at 46 to the oscillating frame and is pivoted at 47 to the knife holder 44, causing the knife 48, carried by the holder 44, to make a shear cut. The movement of the knife holder is produced by a p air of pitmen 44 one at each end of the ho der, said pit.

men being connected at their other ends to the drive shaft 3 which causes these ends of the pitmen to move in the path of a circle as shown in Fig. 4 and consequently to reciprocate the knife on its oscillatory frame and to oscillate said frame. This oscillation of the frame causes the knife 48 to take the path of an ellipse. To neutralize the concave effect of the crank throw during the cutting part of the knifes movement (see heavy part of the circle in Fig. 4), the links or levers 36 are provided with lateral extensions 49 on the sides of their pivots opposite to those sides on which the oscillatory frame is pivoted, and the oscillatory frame carries parts in the form of adjustable set-screws 50. At the beginning of the cutting part of the knifes movement, the screws 50 begin to engage the we tensions 49 on the levers or links 36 and a further inward movement of the oscillating frame shifts the fulcrum or pivot of the oscillating frame in opposition to the springs 39 so that the knife makes a straight out. So that the knife may be properly set to the throat cutting plate 33, either when the ma chine is first set up or when the cutting plate 33has become worn, I provide means for effecting the shifting of the fulcrum of the oscillatory frame to and from the cutting plate, said means being in the form of set screws 40 which limit the inward movement of the links or levers at their upper ends, due to the action of the springs 39.

Sharpening mechanism.To the lower edge of the front plate 43 of the oscillating frame is bolted a depending hanger 51 in the lower end of which is swiveled a bolt 52. This bolt has the lower end of a link 53 pivoted to it, the upper end of said link being pivoted to a bolt 54 which is swiveled in the end of one arm of a bell crank lever 54. Bell crank lever 54 is pivoted to the knife holder 44 on an angle corresponding to the angle of the knife edge and has its other arm pivoted to an abrasive holder 55 by means of a bolt 56 which passes loosely through the arm of a bell crank lever and a hollow stud 57 on said arm, a helical spring 58 surrounding said stud and bolt and bearing against the holder to maintain the abrasive material yieldingly against the beveled knife edge. The abrasive holder or member 55, which may contain a single strip of abrasive material 59 or a number of sections, is further supported from the knife holder 44 by means of an arm or link 60 which is also disposed at the same angle as the arm of the bell crank lever being pivoted at 61 to the holder 44 and connected to the abrasive holder 55 by a bolt 62 which extends through a hollow stud 63 on the arm. A helical spring 64 surrounds the stud 63 and bolt 62 and assists in maintaining the abrasive material yieldingly against the knife edge.

The operation of the sharpening mechanism is as follows: The link being connected to the oscillating frame and the bell crank being connected to the knife holder, it will be apparent that the knife holder is adapted to reciprocate the abrasive member 55. Vhen the knife descends, the abrasive material will be moved vertically away from the cutting edge to permit the cutting of the tobacco to take place and when the knife ascends, the same will be moved to the cutting edge. As the knife moves sidewise during its reciprocation and as the abrasive material also moves sidewise due to its being (iii supported by the arms, the abrasive material will rub sidewise on the edge of the knife, and this sidewise movement is amplified owing to the knife and the abrasive material moving simultaneously sidewise in opposite directions.

It will thus be seen that I have provided a sharpening mechanism which automatically sharpens the knife after each cut.
